The North Africa series of US Silver Certificates was issued in November 1942 in denominations of 1, 5, and 10 US dollars. The notes were similar to standard circulating silver certificates, except for their bright yellow seals. They were circulated amongst US troops in Europe and North Africa during World War II, and intended to be demonetized should the American forces be defeated.
Shown here is a $1 note, which depicts the first President of the United States, George Washington and carries the signatures of William Alexander Julian and Henry Morgenthau, Jr.
